Assessing Body Temperature - Rectal01:27

Assessing Body Temperature - Rectal

14.3K
Rectal temperature measurement is considered the most precise method for assessing core body temperature and typically registers higher than oral temperature. For adults, the rectal thermometer should be inserted 1 to 1.5 inches into the rectum to obtain the most accurate reading.
Follow these steps for rectal temperature assessment:
Step 1: Perform hand hygiene and don clean gloves to prevent cross-infection.
Step 2: Position the patient in a side-lying position to better visualize the rectal...

Increased Body Temperature

7.6K
A body temperature above  38°C  (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

Homeostatic Imbalances in Body Temperature

4.4K
Hyperthermia occurs when the body's temperature becomes unusually high, often due to heat exposure, intense physical activity, or certain illnesses. This condition can create a dangerous cycle where elevated body temperature increases the metabolic rate, generating more heat and potentially leading to organ failure and brain damage. A severe form of hyperthermia, called heat stroke, can raise body temperature to life-threatening levels. Fever, on the other hand, is a controlled form of...

Decreased Body Temperature01:29

Decreased Body Temperature

1.2K
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

Methods of reducing fever01:22

Methods of reducing fever

1.5K
The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Thermoregulation01:26

Thermoregulation

3.0K
The human body has a sophisticated thermoregulation system that employs negative feedback mechanisms to maintain an optimal core temperature. When the core temperature drops, peripheral and central thermoreceptors send signals to the hypothalamus, activating the heat-promoting center. This center triggers several responses aimed at increasing the core temperature. First, vasoconstriction reduces the flow of warm blood from internal organs to the skin so that the heat is not lost from the skin,...

Summary

Misoprostol can cause severe hyperthermia, tachycardia, and encephalopathy in postpartum patients. Clinicians should consider misoprostol toxicity in patients presenting with these symptoms post-delivery.

Area of Science:

  • Obstetrics and Gynecology
  • Pharmacology
  • Critical Care Medicine

Background:

  • Misoprostol, a prostaglandin E1 analog, is frequently used for postpartum hemorrhage (PPH).
  • Commonly reported side effects include fever, chills, nausea, vomiting, and diarrhea.

Observation:

  • A postpartum patient developed severe hyperthermia (41.5°C), tachycardia (170s), rigors, and transient encephalopathy 30 minutes after 800 mcg rectal misoprostol for PPH.
  • The patient's condition required intensive care with antibiotics and cooling measures.

Findings:

  • The patient's vital signs normalized within 7-8 hours.
  • Extensive workup for other causes of her symptoms was negative, suggesting misoprostol toxicity.

Implications:

  • Consider misoprostol toxicity in postpartum patients with hyperthermia, rigors, and tachycardia.
  • Judicious use of misoprostol is recommended due to potential serious adverse effects and limited evidence of efficacy in PPH.
